A Norwich City Q&A session with supporters was designed to give details of its plans to improve and expand Carrow Road - but descended into chaos and chants of "you don't know what you're doing".
The club wants to relocate more than 3,000 fans as part of the long-term project.
But season ticket holders, some of whom have been in the same seat for decades, vented their frustration at losing their spot to new corporate spaces, without consultation.
The proposed changes were laid out for fans at the meeting on Wednesday night, but were met with a heated reaction.
